We have changed provider from Gaming deluxe to Gameserver. I am not sure if this will fix our problem. Any updates about this situation? Is there any other complaints about this to you guys? Gamingdeluxe said they had more people with the same problems but they are blaming the bohemia.

Hello Kathara2012.
The issue is currently being tested on internal branch and so far our server that has been running for 7 days straight still has all the tents / barrels even through various server restarts. If there is any info you could share that could lead us towards reproduction of the issue, please post it here as soon as you can.

Absolutely foaming mad right now. My clan had a camp of over 10 Military tents and several barrels that we collected over a period of 3 weeks. The reset that occurred last night deleted all of the tents without exception. Some tents we had, had barrels within them and the barrels (w/ holes) remained in their place with the correct gear within them. We made sure to manipulate the contents of the tents DAILY to be sure that the tents wouldn't despawn from lack of interaction. The camp was on a public server that we kept online at all times, it was just hidden well. The server did a natural restart twice every 24 hours. We made sure the tents were placed on completely FLAT ground only because we had tents on sloped land despawn before in this update. All tents disappeared at the same time regardless if they were new to the camp or older ones we've had since the update came out.

Our provider is Gameservers however I do not believe the provider is the issue, because if persistence was broken for the provider then even the barrels should have disappeared. We did notice that camp was getting so big that when we would leave the area the frames/second would drop as the tents left our render distance. I think that there is a protocol in the game that don't allow camps to reach a certain size, I base this on nothing.

Maybe the size is a factor. We seem to lose our bases after they are reaching a pretty good size. My guys are constantly pvping and bringing stuff back and I am trading for items as well and we lose them after lots of work and filling them with loads of gear and clothes.

Thank you for the responses.
The camp on our test server is over 10 tents and six barrels in size, also some of them are filled with items completely. We will keep investigating but as I have mentioned before, if you come across any more useful info please post it in here.

I think it's related to the restarts of the server. I don't know who things are saved but somehow maybe the server isn't reading any items on the server when it restores itself or comes back online. I am just thinking out loud here but we lost them after restarts so it's definitely connected somehow. I believe the entire server lost the persistence as one more than one occasion we had more than one base affected. I also think I remember once there was no loot at all on the server.

I would suggest just testing restarts over and over again to see if it happens to you guys. There is something buggy with it in my opinion. I will give you some examples of what happened to us so you can see different scenarios.

1. Server restarted and then everything was gone.
2. Server restarted and everything was gone except for a barrel with holes in it.
3. Server restarted and everything was gone but there were some items we threw away 5 minutes earlier still on the ground.

This all leads me to believe that the normal loot is ok but the persistent items were not for some reason. I don't know if this lies with the actual servers themselves or with you guys. Maybe you could add something like a save feature that saves everything before a server actually can initialize the restart to fix this.
